HEPA air purifiers may boost brain power in adults over 40

Using an in-home HEPA purifier for one month spurs a small but significant improvement in brain function in adults age 40 and older. That’s the result of a new study we co-authored in the journal Scientific Reports.

HEPA purifiers—HEPA stands for high efficiency particulate air— remove particulate matter from the air. Exposure to particulate matter has been connected to respiratory and cardiovascular illnesses as well as neurological diseases such as Alzheimer’s and Parkinson’s. Environmental health researchers increasingly recommend that people use HEPA air purifiers in their homes to lower their exposure to particulate matter, but few studies have examined whether using them boosts mental function.

We analyzed data from a study of 119 people ages 30 to 74 living in Somerville, Massachusetts. Somerville sits along Interstate 93 and Route 28, two major highways, resulting in relatively high levels of traffic-related air pollution. This makes it an especially good location for testing the health effects of air purifiers.

MicroRNAs as Biomarkers in Spinal Muscular Atrophy

Spinal muscular atrophy (SMA) is a severe neurodegenerative disease caused by the loss of the survival motor neuron (SMN) protein, leading to degeneration of anterior motor neurons and resulting in progressive muscle weakness and atrophy. Given that SMA has a single, well-defined genetic cause, gene-targeted therapies have been developed, aiming to increase SMN production in SMA patients. The SMN protein is likely involved in the synthesis of microRNAs (miRNAs), and dysregulated miRNA expression is increasingly associated with the pathophysiology of SMA. Currently, there is a lack of reliable biomarkers to monitor SMA; therefore, the search for novel SMA biomarkers, including miRNAs, is crucial as reliable tools are needed to track disease progression, predict the response to therapy and understand the different clinical outcomes of available treatments.

Treatment of Follicular Lymphoma With CHOP and Anti-CD20 Therapy

Fifteen-year follow-up from the SWOG S0016 trial indicates that a subset of patients with advanced-stage FollicularLymphoma can achieve cure after first-line chemoimmunotherapy with cyclophosphamide, doxorubicin, vincristine, prednisone, and anti-CD20 therapy.

Cure modeling estimated an overall cure rate of 42%, with relapse rates substantially declining over time and highest cure likelihood in patients with low Follicular Lymphoma International Prognostic Index scores and normal β2 microglobulin levels.

This secondary analysis examines 15-year follow-up data from a randomized clinical trial to evaluate the potential for long-term remission and cure for follicular lymphoma following chemoimmunotherapy with cyclophosphamide, hydroxydaunorubicin/doxorubicin, oncovin, and prednisone/prednisolone (CHOP)–based regimens.

FDA approval of Regeneron’s hearing loss gene therapy breaks barriers

Regeneron’s AAV gene therapy for congenital deafness has been approved by the FDA — a clinical victory for helping patients and an exciting milestone for gene therapy in general!

Approved Thursday via the FDA’s Commissioner’s National Priority Voucher program, Otarmeni is the first gene therapy for hearing loss—and the first treatment to target an underlying cause of the condition.

Arthritis Cure BREAKTHROUGH: Regrow Young Cartilage

Stanford published a paper in Science showing they regrew joint cartilage in aging mice — and in human tissue samples taken from knee-replacement patients — by blocking a single enzyme called 15-PGDH. It’s being hyped as the end of knee and hip replacement surgery. The science is real. The hype is getting ahead of what the paper actually says.

This episode walks through the study itself — the three experiments, the surprising mechanism (which doesn’t involve stem cells at all), and the actual clinical timeline.

Bottom line: the mechanism is a genuinely new paradigm for tissue regeneration. The human osteoarthritis trial? \.
